• Turn on the tap and measure the volume of water flowing out of the outlet of the fine filter: Replace the fine
filter if the volume is less than 1 l/min.
The fine filter should generally be replaced once per year; more often in case of poor water quality.

9.2 Active carbon filter
The active carbon filter should be replaced once per year, in case of heavily chlorinated tap water (smells of

chlorine!) every 6 months.
9.3 Replacing the fine filter or active carbon filter
• Turn off the tap.
• Detach hoses from filter (see also point 10) and unscrew fittings.
• Remove the old sealing tape from the fittings. Wind approx three turns of Teflon tape (available in all DIY
stores) around the thread of the fitting in the opposite direction to the thread. Screw the fittings into the new
filter. Please note the general tips on fittings (see section 10).
• Mount the filter in the same position and reconnect all hoses.
• Turn on the tap and check that the system is watertight.

11 What should you do if... Troubleshooting
11.1 If the system leaks...
• between the fittings and the container:
Carefully screw the fitting in a further half to single turn. If that does not remedy the fault, you will have to
reseal the fitting using Teflon tape. See also sections 9 and 10.
• between the hose and the fitting:
Remove hose, cut off approx. 2 cm straight and reinsert (see also point 10).
• at the membrane container lid:
Release the hose connector and unscrew the lid. Check whether the O-ring is properly in place or is cracked
and if necessary install a new O-ring. Grease the O-ring lightly with Vaseline and tightly replace the container lid.
Reconnect the hose.
